support/testing/tests/package/test_kexec.py: fix kexec test for qemu 5.2
The commit f69c972ae6 (support/testing/tests/package/test_kexec.py:
new runtime test) was tested locally with a qemu version (>= 7.x) more
recent than the one available in our buidroot/base Docker image (5.2).
As a consequence, that test fails to run in gitlab-ci as reported by [1].
Remove "dtb-kaslr-seed=off" from the Qemu command line and pass
a custom devicetree to qemu virt machine. This devicetree is
based on qemu aarch64 5.2 dts with kaslr-seed set 0.
The qemu aarch64 devicetree has been exported [2] and updated with the
following method:
qemu-system-aarch64 -machine virt -machine dumpdtb=qemu-aarch64-virt-5.2-machine.dtb
dtc -I dtb qemu-aarch64-virt-5.2-machine.dtb > qemu-aarch64-virt-5.2-machine.dts
edit the dts and replace kaslr-seed parameter by "kaslr-seed = <0 0>;"
As soon as our buidroot/base Docker image is updated and a newer qemu version
is available, we can safely revert this change and use the initial method.
